I think Sonic Wing Mode is but not sure about regular super mode, eos Sonic Wing was able to break through and deck the giant super powered Master Galvatron
That barrier was able to tank some of Primus’ attacks (granted Primus was nowhere near 100% iirc and various characters were juked up off his own power)
Apparently he also beat super starscream in that form which I didn’t remember
With Rhisling he’s stronger than either Master Galvatron or SS though
he also survives the Black Hole in the manga but the Unicron Singularity is extremely bizarre to scale, doesn’t really make you universal or more for just surviving in it or anything, and various other characters can tank being inside it for some time (even Soundwave does in the comics and he isn’t super strong relatively speaking)
