Okay, so yesterday night I thought of how I would handle the triplets' or the Beagle Boys' individuality in my own works. And I came to the conclusion I would make them a hive mind 90% of the time, but make it so they each have unique characteristics that are consitent throughout every story, that are also not very noticable on a casual read.
And then I jokingly said I am going to give characteristics like that, to every member of the Beagle Boys that appears in my favorite Uncle Scrooge story; Only a Poor Old Man (all 9 of them!).
So, of course after making such jokes I decides to actually do it, and I spent 90 minutes researching and writing this, so here you go!
Firstly 176-831: he is the goofball who things often tend to workout for. The reason is because he goofed off and went fishing and found Scrooge's hding spot along the way.
Now for 176-824 and 176-825: 176-824 is a pretty good liar who is always pretty suspicous of Scrooge while 176-825 always goes along with 176-824 and spoiling his lies with obvious "wink wink" behaviors. The reasons are that in this panel 176-824 makea a pretty natural lie, while 176-825 makes it seem obvious it's a lie. The reason for 176-824 to be always suspicous of Scrooge is that he was the one directly lied to when Scroogw told the Beagle Boys to jump in his money (and they broke their heads because of this). So I think it makes sense it would turn his suspicios of Scrooge.
Continuing to 176-840 and 176-830: 176-840 is the planner and sort of leader and 176-830 usually tags along to 176-840 and likes to listen to his plans in order to help. The reasons are that 176-840 is the one who came up with the plan who ultimately beat Scrooge, and 176-830 is the first one to take action in executing the plan after 176-840 told them about it.
Now, for 176-838 it's quite simple: 176-838 is a very proud Beagle Boy who will always lift up his kin (sometimes into defeat). The reason is that in this panel, when Scrooge beat them in eveey turn, he is the one that tells his brothers they haven't l lost yet!
176-836 is the most practical Beagle Boy who wants usually wants to get away with the score as soon as possible (but he still falls to Scrooge's schemes most of the time). The reason is that after beating Scrooge, his first thought is to go to court and claim his money, very practical.
With 176-837 I think it's kinda funny: 176-837 would be the one usually the Beagle Boys depend on to help them out in the last minute, their trump card, if you will, even though he screws up every time and doesn't seem to have any special talent. The reason is that his only appearence in this comic is this panel, he shows up at the very last minute and makes no impact, the Beagles still lose.
Finally, 186-811: 176-811 is the slacker who does nothing for the team and mostly hangs out in the background. The reason is basically that he doesn't appear anywhere besides the lines I recently discovered that imply 9 Beagle Boys in the story, and maybe this blurred(?) number in this panel, and he does nothing in that one either, so I think it makes sense for him to be a slacker.
I actally discovered his existence only a few days ago when I realized those lines look like the rough Beagle Boys to the right of them, and the colorists probably just didn't notice! I originally wanted to male his number 176-832, because that is the average of all the Beagle Boy's numbers here, but I then discovered that in the last panel shown, you can barely make out 176-811, so I decided to go with that.
So yes, to answer your question: I am clinically insane.
