When we are bored...

... we like to do Boss Battle !!!

Well it seems Asriel regain his true form after the ending, with some of his power. Frisk who is already master at dodging, can't say no when Asriel asks him for a rematch (because he knows his moves). Toriel hates it when it happens, since half of the house usually gone after the battle.

Just so you know, I rarely draw comics fully. So this pic might be one of my first tries.
