1 Death of Insanely Overpowered Fireballs: Right. It’s the three of us against the forces of Chaos. A Power Trio for the ages!
2 Death of Inhaling Hatmaking Chemicals: Trio? Hwait on, guv. There’s somefink we need to settle first.
3 Death of Choking on a Giant Frog: Who the leader is?
3 Death of Inhaling Hatmaking Chemicals: Nah. Much more important.
4 Death of Inhaling Hatmaking Chemicals: ’oo’s the Id, ’oo’s the Ego, and ’oo’s the Superego?
4 Death of Insanely Overpowered Fireballs: What?
4 Death of Inhaling Hatmaking Chemicals: ’oo’s the Spock, ’oo’s the Kirk, and ’oo’s the McCoy?

I originally had this strip end at "Superego", but during construction I added the following two lines by way of further explanation.

Now I'm not so sure if that was a good idea or if it was better left less explained.

Anyway, if you're still confused, this is playing off the following fiction tropes: Power Trio, Freudian Trio, The Spock, The Kirk, The McCoy.
