I can see this happening during this:

Venommyotismon: hah! Hedgehog brat! Think you can win against me?! I am far stronger than you in every way!

Sonic: (pulls out a digivice with the data of the Royal Knights) yeah, bootleg internet Satan? You may wanna rephrase that.

Venommyotismon: (realizes sonic can biomerge won the RK) don’t you even dare!)

Sonic: Magnamon! Biomerge with me!
