This would be an awesome fight, especially because I think Val is supposed to be about the same level as Syla and Indra in terms of strength. It's hard to tell how Val compares as he is both wounded severely, and it's hard to say exactly how his power would match up against theirs. Though I'd imagine that while slow, his antimatter could likely even deal with Indra's strongest lightning attacks.
Of course, we'd have to get an ability or abilities even more broken than everything that Syla had if we want to be able to even survive. It'd be an awe inspiring fight though, and it could even be like the Deryl and MC fight against Cole. Both putting forth their best efforts, Val blocking to keep us from exploding, us acting as a decoy to let Val connect some of his strongest attacks. In the end, we barely win, or even only force him to retreat with Val sacrificing himself to protect us so that we can become strong enough to beat Indra at a later time. Val seeing Syla in the Other World one last time before allowing himself to pass on. It'd be an amazing fight no matter how it ended up, though I imagine it would have to end with Val dying no matter how else the battle goes, because H.E.R.O. wouldn't generally let monsters roam free.
Another fight I'm really excited for would be Bernhardt vs Indra. The strongest traditional superhuman (because we don't know how Henri's powers really work) vs the (probably) strongest non god monster would be a fight for the ages. It would probably be the only way for H.E.R.O. to find out the real strength of Indra. Hell, Malik might not even be able to fight alongside Bernhardt due to the potential difference in power between the two.
