Day of Blood starts out pretty strong. By which I mean there is a rollcall page featuring the main characters of both "Star Trek" and "Star Trek: Defiant", and on it we learn that Shaxs once punched a Gorn so hard it exploded.
Hell yeah, he did.
Anyways! It's the big Summer crossover event. The crews of the USS Theseus and USS Defiant come together despite their (extremely flimsy) antipathy for the big showdown with clone Emperor Kahless. It's fun to see the two crews interact for the first time since Worf left the Theseus. We got Tom and B'Elanna reuniting. We got Data and Lore. We got Shaxs and Ro. We...got Lili Sato and the Orion drug-dealer/medic, I guess. We got Doctor Crusher telling everyone to put their collective bullshit to the side and get ready to save Qo'noS. One thing that stood out to me is that T'Lir tells Spock they only know him by reputation, but early in "Star Trek" T'Lir claimed they met Spock as a child. Of course, T'Lir would not want Spock to know they'd met before, because T'Lir is actually Trelene, and if they're not I will it a tricorder toy.
Also, these comics might as well be called "Star Trek: Fanservice", but there's a moment featuring

I’ve been reading the ones that catch my eye for a while now, but the current books involved in this crossover are what really got me from guy who likes both Trek and comics to being interested in actually following Trek comics.
They’re just such blatant fan service in a way that does not feel at all cynical. Big fun.
