I kinda like how this is forming up. Basic set up clone who got free and went to the shadows. But in the three different examples you liked they have different paths.
Daddy Issues Clone: You have a disappointed dad, of the Vader mold, who does not take failure. His son did not cut it and that cannot be the last chapter in Dads legacy. Son may have folded to pressure thru suicide in face of mega dad, gone defiant and went over to his enemies earning scorn, or just sits defeated and broken in his dads house being pathetic in his dads eyes. Mega dad has to be a mage since he was breeding for magic success as the focus. He makes mage clone son to stand in for his son and eventually replace son. Clone may have had magic tudor to get clone on track make sure he would work out this time. Cover story of son learning ancient secrets in secret. Then clone goes missing. Unless this is a second string clone, back up, there will much splaining to do when clonie goes missing. You can play it has Mega dad is a enemy trying to wipe out the clone embarrassment. Clone A is rival and dad is going to give it a year and make a final cut sudden death style. You could go Man in the Iron Mask and have clone seasoned into a bad A then helped to take place of Clone A or the original if he is still there. Clone has heavy drive to master magic and survival skills to a big showdown down the road, with his Run team if they owe him enough. Street skills, magic groups, astral groups, and borrowed time could start him off.
Good Twin Clone: has to live with being thought of famous runner with lethal rep. Again magic is themed and since not much can be detected all will assume clone is cloaking it somehow. Somewhat like the Man Who Knew too Little with Bill Murray where every success will seem a master stroke and all failures like clone must be setting them up. Works til Bad Twin tires of his stalking horse or comes up with a purpose for him (Retirement thru faked death, etc) Maybe criminal SINner, Evil Twin, Rep, distinctive style or first impression to mimic memorable Runner look. Evil Twin has to send a runner, preferrably a hot ex-gf runner, to keep him alive and teach him enough not to ruin the joke to soon. He may want to Dread Pirate Roberts with the clone if he isn't killed by a enemy really soon.
Mr. Betty Clone: This clone may literally be the clone of a jerk who dumped Betty. She may have had him made, her dad may have made him to shut up Betty, or jerk made him to have his cake and eat it too. Could you make a clone of yourself to marry it to a loaded girl so you could live set for life off the trapped clones new wealth? Then the clone escapes just before you needed to use it but then you hear of him running the shadows. Now your trapped married but maybe you can still work the switch if you can just catch that clone.
I don't know which one to work up first.
