With the DigiEgg of Friendship, V-mon evolves into a four-legged beast howling with thunder. His actual name is Lighdramon in Western localisation.
As with Fladramon, this was an opportunity to play with the elements of electricity and fire respectively. As a theme, I use the secondary colours of the spectrum - and in this case, I use the cool, neon vibes of purple.
This took much longer than I wanted it to, laziness. But it looks cool in the end - where as Fladramon was replicating lighting from a fire, this takes into account spots of intense light from the cracks of electricity.
Because Imperialdramon's pose felt boring, lesson learnt: I went the extra mile and made Raidramon kneel, roaring as lightning discharges from himself.
