We are going to analyze the new line of aspects "Omega Squads" that do not have much to be announced and are already floating around there several theories with much sense on the history of this line of aspects that make a lot of sense, but without further preamble Let's see what they are!
Teemo learns from them before being of the Omega Squad (as it is seen in the Splash Art of all), they die and for that reason he is left alone, "Before followed a code"
Her captain was Tristana, Teemo and she fall in love, as she dies he becomes totally mad and full of anger, "Never fall in love".
Veigar was his closest friend, so when he dies he takes his mask and uses it as his own (see Splash Art de Veigar and Teemo)
Seeing that Twitch grenades serve as deadly traps, modifies them and creates the fungi we know in their skin, it also seems to take the Lenses or Binoculars (not exactly as they are called xD) as they can compare in the Splash Arts of the 2, also seems that the weapon of Teemo was a combination between the weapon of Veigar and Twitch (the poison of Twitch and the weapon of Veigar)
The Splash Arts look like old photographs, they could be photographs kept by Teemo Omega Squad, and the character of this Teemo was a consequence of watching his comrades die (as mentioned above)
This has been the end of this post. See you!
