have you seen their tires?

I love this page, it's literally just

starscream takes advantage of desperate tank

It has been shown in the comics that they could get their hands or even head replaced as a form of punishment called empurata.

So in theory, transformers could install another thing like for example a new voice box. Although some could be sparked with desirable frequency, such modification itself would only be limited to the higher class. That is why most of the rich had a nice voice.

Other installments I could think of are the glossa and lip plate. Imagine a bot with a 7 feets long snake tongue. Maybe other less insignificant thing like extra digits or just straight-up getting toes for the fun of it.

May the immage of Bumblebee with toes will forever haunt you

735,306

Homestuck ships possible (don’t forget, four romances, one tri-relational) = (840 * 839 * 3) + (840 * 839 * 838) =

592,703,160

594,820,800

This is of course assuming that each character is only capable of having 4 types of ships.  If we factor in charms (which is the Leprechaun romance system) there are 9 types of relationships. However, it is clearly stated that Leprechauns can be in more than 1 charm with another Leprechaun. That means that the total number of combinations of relationships that a Leprechaun can have is :

 = 

511

There are 14 known Leprechauns in Homestuck meaning that the total number of possible “Leprechaun Only” relationships in Homestuck is (14*14*511) = 

100,156

So we add that number to the previous total for 594,820,800 + 100,156 = 

594,920,956

However, this is assuming that only Leprechauns can be in these types of relationships. If we assume that all characters can additionally be in these types of relationships (which I understand is a big assumption, but the fandom will probably ship everything possible anyway) then we need to add a few more numbers.

(840 * 840 * 511) =

360,561,600

I am going to add this to the first total I came up with so as not to include the Leprechauns twice. So the grand total number of ships possible in Homestuck assuming that every character can be in both Troll and Leprechaun relationships (but not both at the same time) is:

594,820,800 + 360,561,600 = 

955,382,400

So remember how way back when I said G1 has 538 Autobots and 452 Decepticons? Remember that? And how I got that nifty calculation that said, hey the Transformers Fandom has nearly 3 billion ships in the G1 Continuity on its own? 

Well, I went back onto the TF Wiki and decided to calculate the total number of characters from every continuity that could be considered Cybertonian in origin.

TOTAL NUMBER OF AUTOBOTS = 3071

TOTAL NUMBER OF DECEPTICONS = 2469

TOTAL NUMBER OF MAXIMALS = 264

TOTAL NUMBER OF PREDACONS = 310

TOTAL NUMBER OF NEUTRALS = 40

TOTAL NUMBER OF MINICONS = 610

That is a grand spanking total of 6764 Cybertronian characters. If we were simply to address one specific method of pairing characters, say Full Spark Bonding between two individuals, this would lead to exactly 91,503,392 possible ships.

However, there are five widely observed types of relationships between Cybertronians. These are Full Spark Bond (2 Individuals), Partial Spark Bond (2 Individuals), Trine Bond (3 Individuals), Full Multiple Spark Bond (3 to 5 Individuals), Partial Multiple Spark Bond (3 to 5 Individuals).

Ahem.

Following my revised calculations, the total number of possible ships with JUST Cybertronian Characters is anywhere between 2,785,363,252,480 and 929,033,938,976.

Between 2 Trillion and 900 Trillion. 

In conclusion…

ROBOTS!!
