more like low Multi 5D+ with Mftl+ speed Just look at the dimensional statements,Aizens sweeper feat,Yhwach / SK feats or squad 0 bankais not to mention Ichigo was ftl pre ss already.
@BronyLord-wo1ym I've not seen Megatron move faster than light or seen Megatron break the laws of their own universe. Ichigo blowing a hole through hell( supposed to be impenetrable ), into the living world and then breaking through that world and blasting into the soul society, also supposed to be impenetrable, all in one go while also not in his final form is probably a bit more impressive than evil robot who gets beat up half the time.
Megatron infected by Dark Energon won't help him win the the fight at all. As Ichigo's spiritual energy is far beyond powerful then the blood of Unicron. But dark energon will allow Megatron to put up an extra fight against Ichigo. Megatron better pray that Vasto Lorde does not unleash itself from Ichigo Kurosaki, Otherwise Megatron can kiss his life goodbye!
