Ekatotessera's name is taken from the Greek phrase for 'one hundred and four', "ekató kai téssera", a reference to the fact that he is based on the real galaxy Messier 104, the Sombrero Galaxy.
Ekatotessera's alternate name, Halon, is based on the fact that he resembles a halo.
Ekatotessera closely resembles the real world Messier 104 (M104), the Sombrero Galaxy.
Destined to be G-Rex's shield, Ekatotessera would have served alongside Aetherium, and thus was the second creation of G-Rex, and was created by the latter an unknown amount of time after Aetherium came to be. However, the sentient universe quickly realised that Ekatotessera was of no use to him; the galaxy was too timid, and too weak to serve any purpose. Banished by Aetherium, Ekatotessera fled deep into the voids of Universe 1, and hasn't been seen since.
Ekatotessera, referred to by the humans of Universe 1 as 'Halon', is set to appear in the second 2017 Christmas Special, On The Second Day of Christmas. In this special episode, it is explained that he ended up in Universe 1 after being pulled through the rift Aetherium created to enter the universe during the Season 2 Finale.
- Defensive Powers: Ekatotessera can presumably take the form of a giant shield, the counterpart of Aetherium's Blade Form. However, due to his non-desire to engage in combat, Ekatotessera has never actually taken this form.
- Voice of the Void: Ekatotessera can create visions of events happening in alternate universes and timelines to those he chooses to communicate with.
- Once again, Ekatotessera's creation shows you guys just how much I think space is incredible. M104 is one of my favourite galaxies in terms of appearance, so it's unsurprising to me that I'd use it to help inspire the creation of a new monster in my library!
