MetaKnight dimensional cape glitch.

Copypasta.

Those in the Meta for
God Tier thread have already seen this. Someone said they pulled off
this technique for up to a minute. Quite frankly, I don't even think
there's an upper time limit on pulling off the trick (at least until we
learn the exact mechanism for how this works), which means that once
mastered, Meta can become the best staller and virtually dodge every
single attack. Seriously, invincible and invisible? Potentially up to a minute? Hell, you could dodge a pro's Sonic's FS with that. Sonic's for God's sake!
