Blood Brothers

Power Level:
Game system: DC Heroes Role-Playing Game


The Blood Brothers are minor Marvel alien enforcers. They are chiefly remembered for having worked for Thanos – their first appearance was also Thanos’.

These are older technical notes, not a full profile. We’ll overhaul this thing when feasible.


  • Real Name: Unrevealed.
  • Marital Status: Single.
  • Known Relatives: None.
  • Group Affiliation: Thanos’ mercs.
  • Base Of Operations: Mobile ; occasionally Sanctuary II when Thanos was its commander.
  • Height: 8’ (although as usual they are drawn taller – more like 11’). Weight: 900 lbs.
  • Eyes: Red Hair: None


Powers and Abilities

The Blood Brothers are two superhumanly strong aliens. They have a gift for brawling and leg breaking.

Due to their power of symbiosis, the closer they are to each other, the more powerful they are. Thus, the best way to defeat them is to separate them.

The Brothers are also highly practices at fighting unarmed as a duo, allowing them to defeat powerful opponents.


This pair of enforcers were among the mercenaries assembled by Thanos. They were often entrusted with minor missions involving brawn. Their fighting track record is nothing to sneer at, with victories against Iron Man (Tony Stark), the Thing (Ben Grimm) and Hercules (Herakles).

The Blood Brothers rampaging

When Thanos’ empire fell, they were imprisoned in the Vault. Thanos’ tech had been modified by Avengers to keep the Brothers depowered. They left the Vault at Quasar’s request, only to end up stranded on Mars. How they came back to Earth is unclear, but they were back during the Maximum Security  episode.

For unclear reasons, they killed the Skrull Z’Cann, secretly a Professor X ally, in Salem Center. They later were part of the invasion against the Ruul Kree ship that ended the Maximum Security mess.


See illustrations.


The interstellar equivalent of enforcers for a loan sharking operation. However they are surprisingly articulate, and more adept with ultra tech (such as spaceships, image inducers, etc.) than their brutish appearance suggests.

They have an annoying tendency to relay each other when speaking, quite often in mid-sentence.

DC Universe History

They could have been left being by an uncaring Dominator party after the Invasion . In that scenario they are a roving pair of alien bandits, taking whatever they need, such as food.

Their appearance and outlook is also quite reminiscent of Apokolips. Thus, they could easily be agents of Darkseid and Kalibak, still stranded on Earth after the mission they were sent on was shot to pieces by Green Lantern Hal Jordan.

Design notes

Both Blood Brothers have the exact same stats.

Their reported vampiric ability were never used AFAIK (their teeth couldn’t penetrate the Thing’s hide) – they *might* have low APs of Vampirism.

The Blood Bond

The Blood Brothers get gradually weaker as the physical distance between them increase. This special Power Loss works as follow :

  • Every 3 APs of distance between the Blood Brothers reduce their DEX by one AP. Their DEX is thus 05 when separated by 3 APs, 04 when separated by 6 APs, etc.. Minimum DEX is 02.
  • Base BODY is reduced by one AP for every AP of distance past the first. BODY is 13 when separated by 2 APs of distance, 12 when separated by 3 APs of distance, etc.. Current BODY condition should be kept track of separately. Situations can arise when the current BODY is higher than the base BODY, since the base BODY has been reduced by distance. This is normal. Minimum base BODY is 04.
  • STR is reduced by 2 APs for every AP past the first one. Thus STR becomes 14 when the distance is 2 APs, 12 for 3 APs of distance, etc.. Minimum base STR is 04.
