Cybertron Architecture.
After the victory over the Quintessons, the question of the planet's improvement arose. The Quintessons' buildings were small and corresponded to their anatomy, and the Transformers were in barracks.
Accordingly, the transformers decided to demolish everything and rebuild the planet. Grapple was appointed as the architect.
Even before the uprising, he was an architect-builder (constructicon), but it was after his release that he was appointed chief architect of Iacon
Grapple's style (later called Grapplism) attracted attention with its simplicity, laconicism and asceticism, but at the same time it looked majestic and impressive.
The main features of his style were:

• simple geometric shapes, angularity;
• ornaments based on gears, springs, mechanisms, stars, Cybertronian animals;
• materials: metal, concrete;
• flat images without similar images with poster graphics on paintings.
  Grapple stopped functioning about 300 cycles before the war. In the last cycles, he suffered a software failure similar to human depression, which is why he committed suicide.
