First Appearance of Thanos in Marvel Comics : Part 1 : Beware the Bloood Brothers

Iron Man V1 #55 : Beware the Bloood Brothers

The issue begins with Drax mentally transmitting “a message of fear and dread” for Iron Man.

Drax, from his place of confinement is able to mentally transmit a message to Iron Man. The warning from Drax is “Beware the Bloood Brothers”.

We cut to Iron Man engaged in Battling the Blood Brothers, two burly red aliens as he contemplates the telepathic message from Drax.

The Blood Brothers manage to knock Iron Man unconscious and carry him into their flying craft to meet their “leader”.

The ship takes Iron man to seemingly desolate area of the planet which contains an alien fortress below its surface.

First Appearance of Thanos

Within this Earth Fortress we lean that Drax is held prisoner by Thanos.
From his chains of imprisonment Drax threatens to break free and fulfil is sole life mission – to annihilate Thanos.

The origin Of Thanos

Here we learn The origin Of Thanos.
In the form of a flashback we then see Iron Man receiving the telepathic messages transmitted to him by Drax the Destroyer.

Iron Man Learns about Titan

Drax transmits the story of a secret world within Titan, Saturns largest moon. The Titans live within a self sufficient paradise managed by a gargantuan computer named Isaac. The Titans are thus able to study art science and beauty.

This paradise world is ruled by Mentor and his sons Eros and Thanos. But when Thanos began creating weapons and tried to usurp Mentor in the Great Rift he was convicted of the “crime of crimes”.

As punishment, Thanos was exiled from Titan to never return. However within the usurper, “the seed of evil sprouted and flowered within him”.

Thanos builds an Army

Thanos was committed to vengeance against his home planet and he cris-crossed the galaxy collecting rebellious and dissatisfied warriors to join his army.
