Let’s examine the strength and speed levels across all the series Ainz has collaborated with, detailing their scaling to understand how strong and fast Ainz might be in these contexts.
A Certain Magical Index: Fantasy Convergence x Overlord
• Strength: A Certain Magical Index has characters like Magic Gods who can manipulate reality on a universal or even higher scale, including time, space, and fundamental forces.
• Speed: Top-tier characters possess speeds in the massively faster-than-light (MFTL) range, reacting within nanoseconds or faster.
A Couple of Cuckoos x Overlord
• Strength: This is a slice-of-life romantic comedy with no supernatural elements, so Ainz’s strength remains unchanged or comedic.
• Speed: Human-level speeds, and no upgrade applies to Ainz here.
AFK Arena x Overlord
• Strength: AFK Arena’s high-level heroes can reach city to continental strength, though the power levels are heavily game-based and variable.
• Speed: Characters show superhuman speeds, but nothing on an interstellar or cosmic scale, keeping Ainz relatively within his own power range.
Altina X Overlord Special Collaboration Booklet
• Strength & Speed: Altina is a novel series with political and military themes. There’s no boost for Ainz here, as the series is low-powered with grounded battle mechanics.
Caravan Stories X Overlord
• Strength: This fantasy RPG includes powerful spells, elemental manipulation, and summoning, but scales more around high-country level at most.
• Speed: Characters are fast but remain below light speed, so Ainz’s usual teleportation and spellcasting speed are more than sufficient.
COMPASS x Overlord Collaboration
• Strength: COMPASS characters wield destructive magic and elemental attacks, but strength caps at city-level feats.
• Speed: Reaction speeds are superhuman but not faster than light; Ainz’s teleportation would still be an advantage here.
Crystal of Reunion X Overlord
• Strength: Heroes are capable of country-level attacks and magical feats.
• Speed: Characters move at low supersonic to high subsonic speeds; Ainz retains his speed advantage.
Dragon Egg X Overlord
• Strength: This mobile RPG includes monster taming, with some creatures reaching mountain-level feats, so Ainz is still more powerful.
• Speed: Mostly limited to fast-human speeds, so no scaling upgrade for Ainz.
Dragon’s Dogma Online X Overlord
• Strength: Characters here scale to high-city or country-level threats; dragons and mythical creatures pose a challenge but remain within Ainz’s range.
• Speed: Characters have quick reflexes but don’t surpass Ainz’s own reactions.
Epic Seven x OVERLORD
• Strength: Characters can cast large-scale spells, often around country-level.
• Speed: Some fast reactions and movements, but again, nothing faster than light, so Ainz’s teleportation remains superior.
Grand Summoners x Overlord Collaboration
• Strength: Powerful Grand Summoners characters reach planetary levels, potentially making Ainz approach this scale if he’s given such boosts in the game.
• Speed: Top characters reach hypersonic to light-speed reactions, so Ainz could be upgraded to faster-than-light within this setting.
Heroes Evolved X Overlord
• Strength: Heroes can display city to country-level abilities, with magic and summoning similar to Ainz’s style.
• Speed: Speeds are superhuman but remain below light speed.
Isekai Quartet & Isekai Quartet The Movie -Another World-
• Strength & Speed: Isekai Quartet is comedic, so while characters are powerful, scaling is played for humor. Nothing boosts Ainz’s abilities here to multiversal levels, though he retains his typical strengths.
Knives Out x Overlord
• Strength & Speed: Knives Out is a battle royale shooter; no supernatural boosts are applied here, leaving Ainz’s power unchanged.
KonoSuba: God’s Blessing on this Wonderful World! X Overlord
• Strength: KonoSuba characters typically cap at city-level magic. The deities in KonoSuba are powerful but not close to multiversal.
• Speed: Speed levels are limited to high-human, with a few superhuman feats, so Ainz’s teleportation is an advantage.
Kotodaman x Overlord
• Strength & Speed: Kotodaman is a word-based RPG with puzzle mechanics, and character feats do not affect Ainz’s stats.
Langrisser X Overlord
• Strength: Characters can reach high-country level with magic and skill.
• Speed: Speeds are enhanced to superhuman, so Ainz’s teleportation keeps him dominant.
Last Cloudia X Overlord
• Strength: High-level characters can exhibit city to planetary-level abilities.
• Speed: Faster-than-light reactions are possible, giving Ainz a minor boost in speed within this crossover.
LINE Rangers x Overlord
• Strength: City to country-level, keeping Ainz within similar limits.
• Speed: Speeds are superhuman but not above light-speed.
MapleStory X ISEKAI QUARTET
• Strength & Speed: MapleStory’s characters are often town to city-level in strength, with teleportation but not true faster-than-light speed.
Mass for the Dead Collaboration Events
• Strength & Speed: Directly related to Overlord’s universe; no further scaling is given.
Overlord II X Chain Chronicle 3
• Strength & Speed: Chain Chronicle characters display regional-level power and superhuman speeds, making Ainz’s teleportation a key advantage here.
Overlord X Golem Barbarian Crossover Story
• Strength & Speed: This doesn’t affect Ainz’s strength significantly, as it’s within Overlord limits.
Overlord X Logres
• Strength: Logres characters have high-power magical attacks, but scale mostly to mountain or city levels.
• Speed: Movement is fast, but below light speed.
Overlord X MAH-JONG FIGHT CLUB Sp
• Strength & Speed: Mah-Jong games do not affect Ainz’s scaling.
Overlord X Summons Board
• Strength & Speed: Feats do not increase beyond city-level, keeping Ainz at his base power.
Overlord X Unison League

• Speed: Speeds remain below faster-than-light.
Overlord X Valkyrie Connect
• Strength: Characters scale around city to small country levels with mythological powers.

Seven Deadly Sins: The Battle of Light and Dark - Kongbakpao x Overlord
• Strength: Seven Deadly Sins characters can reach high-country or continental feats.
• Speed: Speeds are high but not faster-than-light, keeping Ainz’s teleportation as his main speed edge.
TalesWeaver X Overlord
• Strength & Speed: Scaling stays around city-level, with limited boosts to Ainz.
That Time I Got Reincarnated as a Slime X Overlord
• Strength: Tensei Slime has characters with reality-warping and continental to multiversal powers, especially at the demon lord level.
• Speed: Higher-level characters operate near light-speed, so Ainz might gain a slight boost but still wouldn’t scale to true multiversal.
Summary
Overall, most crossovers keep Ainz’s abilities within high city to continental levels, with some possible boosts in speed up to light-speed reactions. Only in crossovers like Grand Summoners and Tensei Slime might he reach near-planetary strength or high light-speed, but nothing multiversal or megaversal. This setup leaves Ainz well below SMT or DC’s highest cosmic tiers.
