God among men Edit
It's now quite possible that his ability to survive falls of great distance has been aided by Gil's former swordfighting clank, modified by Agatha to rescue Othar before she discovered his insanity. While Othar had survived at least one fall from a great distance before this clank came to be, the clank might now fly fairly close by him at all or most times, ready to rescue or protect him.
Othar loses fights very, VERY easily despite never dying or even suffering visible injuries. What's up here?
Maybe Othar could have modified himself to be very resilient to damage? This may make him a self-made construct/modified Spark.
The visor Edit
The function of the visor is to protect unsuspecting persons from the influence of Othar's baby blues. (It's probably also easier or more fun to draw.)
Gil and Othar's Adventures in ParisEdit
According to Othar's Twitter (which is considered Canon, but extremely unreliable), during Othar's halcyon college days, he a girl (possibly Zola) through the tunnels of the Paris sewers, but "an inebriated lad with a particle taser and a rubber mask" (possibly Gil). Gil "a dirty fighter, what with all that "winning" all the time."
The similarity of the names is highlighted when we first meet Othar: Agathahim as "the Othar". One of the first things we about the Other's appearance following the attack on the Castle is "Someone was clearly trying to wipe out Europa's sparks."
On the other hand, the Other is Agatha's arch-enemy, whereas Othar is actually helpful once he learns her identity. But the initial appearance of the Enigma can be interpreted to suggest that the Other may not be such an implacable enemy after all.
Reasons for the Hunt Edit
It has been mentioned by the authors (outside of the comic itself, so far) that he was set on his current path by the destruction of Oslo. What this means is unclear, but some have speculated on the motivating power of guilt and the notoriously destructive nature of breakthrough devices.... what is certain is that he is responsible for the Great Wall of Norway, and that the Wall has something to do with his self-proclaimed mission. If it also has something to do with the destruction of Oslo, well... that's rash speculation. Confabulation. (Bloody likely.)
