I’ve been playing Soki/Tekkaman and have been looking for uses for Soki’s assist with Tekka. A few interesting things so far.
First, Soki’s assist easily combos into both 623 Super and Lvl3. Simple combo with something like A, B, C, call assist, 6C, assist hits, super. That’s about 30 trill on its own and could easily be extended for more.
Second, changing the timing of the assist can make some interesting things happen. Depending on when you call Soki the opponent will be sent in different directions. Calling him a little later will cause the opponent to be knocked back towards Tekka to continue the combo. I think this could lead to some big damage but have had trouble landing much out of it, so I’ll keep working on it and see what I can get.
