Please only comment with ONE hidden detail or reference!

There is one Loss, one Balthazar and one crewmate. Bonus panels don't count.

1: You can already spot Sephiroth carrying Pokémon Trainer's Poké Balls in the first panel, as Daniel Myhre did!
2: Another loss for Trigger: the trees in the background of the first panel.
3: Yeah, Sephiroth's rope is barely even doing anything anymore, Generic Hero.
4: Oh Baltabuns can learn Surf, Spirit of Gotham! So he's good, he can leave the island in panel 1 whenever he wants.
5: Fuecoco is scared of the water in the first panel, since he's a  fire type.
6: Sephiroth managed to snatch himself a Cylizar, so all three of them have lizard-mounts now! Only seemed logical to give him one, edmg7.
7: This week's crewmate is visible in the lamp of Sephiroth's Cyclizar saddle, as found by Cameron Devera.
8: Alolan Exeggutor once again makes an appearance: he's visible in the background of the second panel.
9: Squirtle brought a baseball bat to the battle, probably because he can't do much against a Dondozo as a water type. Quaxly is later seen using the bat, so I guess they have put aside their differences, Gianpaolo Reinares!
10: The gang tidied up and put the Christmas decorations in a box, only they forgot to put the box away, since it's still there in the final panel. Good catch, The Negotiator.
11: There's also a leftover champagne glass, as mentioned by Zach.
12: We can also spot the stain of the Hollow Knight Grub that was stepped on by Kazuya in the final panel. RIP.
13: The Mausholds have completely taken over the Smash House and there's a single Maushold being very dad-like, reading a newspaper on the couch, as pointed out by Lord Circe. The newspaper says "MAUSHOLD INFESTATION" by the way, as pointed out by Kristen Shields.
14: Yeah, I'll count it, CSDX. Initially Incineroar was going to be the main character in this comic but I thought it'd be nice to make Sephiroth show off his heart change.
15: I didn't expect anyone to recognize it, but the silhoutte outside of the Smash House is our obscure retro character this week. It's a robot called Thorn from a fighting game from the 90's called One Must Fall: 2097. I played that a lot at a friends house back in the day.
