Modo is the oldest one from the Biker Mice.
Yes. He is older than both Throttle and Vinnie, though he is same aged (23) with Throttle.
Modo`s right eye is bionic.
False most likely. Modo`s eye is most likely biological, only Throttle has bionic eyes. In Biker Mice from Mars Annual from year 1995 do claim that his right eye is bionic but it`s 99% mistake.
But it glows! Doesn`t it prove that it is bionic.
No. Does Throttle`s eyes glow when he gets mad? Nope. And besides if you look some people in the eye when they`re really pissed off their eyes may seem to glow weakly. Modo is that kind of person whose eyes start to glow when he gets really mad at someone. Also we have to remember that in the cartoons some characters are often highlighted or somehow made to appear more stronger than it would appear in normality so the highlighted glowing may be a cartoon trick rather than sign of a bionic eye - a bit like cartoon Batman`s completely white eyes.
Left eye is bionic eye that has been hidden under eye patch because it doesn`t work.
Most likely false. Modo lost his left eye at the same time with his right hand but I suppose Dr. Karbunkle either didn´t have time to put new eye instead of the lost one or he thought Modo doesn`t need new eye because he still had his right eye and he (Dr. Karbunkle) wasn`t sure would the bionic eye work as well as biolocical. As you may already know, Throttle`s eyes don`t work well and he must use either his helmet or his specs.
Modo was once married.
Officially unsure because there were never made an episode where Modo´s past would have been explained. Tom T. - the guy behind the Biker Mice from Mars - told unofficially that Modo would have been married, and from his words some people (including me) have made the conclusion that he would have been married and his wife would have been rat and she may did something that later caused the huge rage towards all rats in Modo.
There is a small nuclear reachtor in the upper arm of Modo`s bionic arm.
I doubthat seriously. Evenif no-one knows where exactly comes the energy that the arm needs but I`m quite sure it can`t come from a small nuclear reachtor that would have been placed into the upper part of Modo´s bionic arm. If there would have been such a reachtor, Modo and his bros would be in continuous death danger in the case that something goes wrong and the hand gets broken. I`m quite sure that if there had been a nuclear reactor or for example nuclear energy batteries that are loaded for example once a month, Modo, Throttle, Vinnie and Greasepit at least would have died in the episode called "Verminator." In that episode Modo´s bionic arm gets broken when Greasepit drives over it and if there had been any nuclear stuff in it, it would have killed those who would have been close enough at first and then those who weren`t close enough to get killed by it but near enough to get sick by it. The whole Chicago would have gotten sick at least in a few years, including Charley, who tried to fix the arm and even Lawrence Limburger, thought he would have finished Chicago before that. Anybody who know the story of Tsernobyl in spring 1986 closely, can (or at least should be able to) imagine what kind of risk it would be to carry a nuclear generator in one´s arm.
Then how Modo can lift heavy thigns with his bionic arm? Where does the energy come from, if not from a nuclear generator or something like that?
No-one actually knows exactly how Modo can lift heavy things with his bionic arm without that it would get broken, but mainly the arm works in the same way as biological hand does. My theory for the energy question is so called "wind generator theory."
The main idea in the wind generators is that when they move and that way proceed the energy, they first full their own batteries before they connect to the electric net and start to send energy to us. By using this knowledge I created my "wind generator theory." And it is not as impossible idea as it may sound at first.
So, by this theory there is small, very light weighted but effective batteries in the bionic arm of Modo´s. When he moves his arm, fingers... (the arm muscles work even when you for example walk, you can`t keep yer muscles still for a long time!) the movements create energy that becomes stored to the batteries and from the batteries comes the using energy. Simpler example may be bicycle`s dynamo. The more and harder you ride your bike the more the dynamo creates energy (for the lamp of the bike).
