#*only science knows

Well I’m human, so wanna test that out?

For some reason, I had a feeling you were going for that. I must know you too well by now.

Oh, sure, I suppose. Why on Irk not?

❤ - Do they have a love interest?

Despite not having an official mission to occupy his time on Earth, and spending most of said days gallivanting around either needling/getting needled by Zim or exploring for the supernatural, which means he technically isn't busy so much, Dib nevertheless doesn't consider these things very much.

So for him, it would likely end up being a thoughtful 'no'.

☮ - Do they have an idol or someone they look up to?

Though the scientist occasionally resentfully laments about being sent to Earth regardless of not being an Invader on the commands of the Tallest, having always been studying information rather than training his muscles since smeethood means Dib can't help but still (both metaphorically and literally) look up to Tallest Membrane, whose views the Irken grew up sharing.

Which is probably why he keeps doing stupid things in the name of science.

☼ - Something that/Someone who makes them happy.

He doesn't have many people willing to voluntarily speak to him, let alone in any hint of a friendly tone, so spending time with Zib is pretty good at making him content, at the very least.

Dib also really, really likes sugar cubes. That will probably make him happy too.

✖ - Who is someone they just cannot stand?

Do you even have to ask this one? Zim, Zim, Zim. The human draws Dib's ire like literally no one else has ever managed, and any kind of death is probably too good for him. Suffice to say the Irken would not hesitate to push the suspicious, stubborn moron with the conviction that he's saving the world from an impeding alien war out of a window given the chance.

... Also, Keef, though that's less 'I hate you please go away' and more that the ever-cheerful Invader honestly freaks the Irken out.

♥ - What does ‘love’ mean to them?

Having grown up as part of the Irken Empire, where silly emotions like love are looked at funny, Dib honestly doesn't consider it at all. His thoughts are usually predominately about his inventions and experiments, so love doesn't mean much to him personally. 

♣ - What is one thing that they find embarrassing? (About them, others, things in general)

Dib finds the concept of acting feral (Purring, scratching, biting) slightly undignified and therefore something he personally tends to pretend he doesn't do. This does not stop him from going right into any fights against Zim with bared teeth and a clawed grip, but if you bring it up once he's calmed down he'll probably act like he doesn't know what you're talking about.

He'll also likely feel violently embarrassed for others if he sees them about to do something both extremely dangerous and, to him, obviously moronic - for example mixing an oxidising agent with reducing ones. Depending on who they are, Dib will probably find the urge to either stop them before he suffers more second-hand embarrassment from their pathetic attempts at chemistry or to directly throw them into the resulting mixture because evidently their intelligence is at an all time low and the world would be a better place without them.

✓ - How do they react to praise?

Another easy way to fluster Dib. While he'll likely recover himself quickly with 'oh, of course I'm the best around', the fact of the matter is that being an Irken hasn't made him any more accepted, so compliments are just as hard to come by for him as his human self.

Can you keep up?

                            Can you compete?

You tip

            and you toe

And you're all ears

                              and I'm all eyes

You take the lead

                            and I'll

                                      take

                                              off

                                                   my

                                                         disguise

Huh?

Oh, Z! Yes, I'm doing perfectly fine.

...wHY.

WHAT DID I EVER DO TO DESERVE THIS KIND OF FATE.

WHICH TALLEST DID I WRONG TO EARN THIS KIND OF SADISTIC COMMAND.

WHATEVER I DID TO WHOMEVER, I APOLOGISE SINCERELY.

PLEASE RETRACT THIS ORDER. DEAR IRK.

...

i. alright, alright. ugh.

WHAT? WHY.

I HAVEN'T EVER EVEN KISSED ANYONE BEFORE IN MY LIFE. AUGH.

THAT'S GOING TO BE FILTHY. AND DROOLY.

AND- AND-

PROBABLY JUST ALSO REALLY DISGUSTING.

... Eugh.
