DC Comics with a side of actual Science

1. Clone a new spleen since he has experience and it’s probably easier than cloning a Kryptonian

2. Capture Vandal Savage and steal his spleen since he’ll just grow a new one

3. Targeted application of the Lazarus pit to specifically the spleen area

4. Tim is a meta with the very specific superpower of regrowing his spleen like a salamander and its tail

5. Steal a spleen from an Arkham inmate because terrorism loses you spleen privileges

Bat Family Answers:

Bruce: “Riddler must be robbing the largest grocery store in Gotham!”

Dickbin: “The only egg I see is your bald head, boomer”

Dickwing: “What does the chicken part mean… The egg part obviously means he’s teaming up with Joker because clowns have eggs but who is related to chicken(s)…”

Jaybin: “The chicken, probably idk. Stupid philosophical question anyway”

Jayhood: *shoots the radio* “Boring conversation anyway”

Timbin: “The egg obviously, eggs are not exact genetic clones of their parents so the first chicken egg was a mutation spawned from a proto-chicken. Since this is a history of nature question, Museum of Natural History?”

Steph: “Hey siri get me directions to the nearest chicken hatchery to Gotham city limits”

Damian: “Neither, as the line between species and their ancestors is not strictly delineated but rather a gradual process. Thus, this question is a logical paradox. We must depart immediately for Mupert Rurdoch’s Gotham Box5 News, as there is no greater example of such paradoxes in the city.”

Cassphan: “What is a chicken?”

Cassbat: “Depends on the person. What is the famous breakfast place in Gotham?”

Alfred: “Eggs predate chickens by millions of years. I cannot purport to know what Mr. Nygma is planning, but this is a silly question.”

Babsgirl: “Chickens - you can’t have an egg without a chicken”

Babscle: “Hey team, just checked, Riddler isn’t even pulling anything tonight, he’s literally just doing this to mess with us.”
