Victor + Ren = Ultimate 10

Victor + Ren = Ultimate 10 is a crossover where the two heroes and Victor Millenicon team up together to fight an evil villian called Vegelance. It starts off where Victor and Ren are fighting in their own worlds fighting against their own villians, equinox and Kenny Tennyson. But up in the sky an evil villian called Vegelance watches them to see how skilled they are. He then produces destruction on both Ren's and Victor's world. Then both Equinox and Kenny are taken away and replaced by Vegelance's minions.

Then both Victor and Ren chase after Vegelance after he attacks them both and end up meeting each other. At first, Victor and Ren start fighting but then find out they're on the same side. When they both go to introduce their best friends, they have suddenly dissappeared and they have an idea of who did it.

Victor slaps his Evoltrix and becomes VictorAnodite to track down where Vegelance ran off to. Victor picks up a trail of his D.N.A and then Victor flies off with Ren as Jetray. They are led to a hidden castle and when they go inside, the place lights up and they see their best friends tortured by their enemies, Equinox and Kenny. Then Vegelance steps to them and they fight. Then at the last few minutes of battle, Victor and Ren's watches form together and form a Megatrix. They then destroy Vegelance and save the day.
