Combine any two for most dangerous Amalgam.

Batman
Wolverine
Spider-Man
Iron Fist
Namor
Captain America
Karate Kid ( last known version )
Lobo
Firestorm
Silver Surfer
Thor
Any GL
Orion
Martian Manhunter
Captain Marvel ( Billy )
Flash Jay Garrick.

I could've added more but which two combined into one being with all of their powers would be the most unstoppable?

Captain America with a GL ring

Surfer and Lobo.

Or GL and Lobo. He's already shown great willpower. That nasty imagination and smarts of his? Pretty good combo.

Firestorm + MMH or Firestorm + Lobo could be pretty good.

GalanFireHunter sets his head on fire, melts and dies.

Wolverine and Jay Garrick.

The only limiting factor on Jay's speed is his possibility of having a heart attack when his pulse gets to high. Having Logans HF takes that away and allows him to match the faster Flashes with greater smarts and experience plus admantium bones and Logan healing, senses, agility. He has shown the ability to speed steal but reluctance to do so for moral reasons (stealing Suoes speed felt like cheating). Amalgamating with Logan's character would also overrite that.

Imp + admantium bones + speed steal + Logan HF with flash speeded metabolism

Jay is honestly the best flash

Orion with the Astro Force plus the power cosmic? That’s gotta be up there.

Captain Marvel with a gl ring woukd be an op force. He has courage, will and clairvoyance of the gods.

The most "dangerous" would be Logan with JG speed tho imo.

Superman+Silver Surfer although it could make Supes weaker.

Lobo+Silver Surfer would be a nightmare.
