I have found an explanation for why jay is weak

A dedicated LEGO fan on Reddit has uncovered a compelling in-universe explanation for why the character Jay from the Ninjago theme often appears weaker than his fellow ninja. According to the analysis, a character's elemental strength directly correlates to their emotional state and willingness to push their limits, specifically noting that angry elemental masters channel significantly more power.

As the generally happiest and luckiest member of the team, Jay typically operates at a lower baseline of intensity. However, the evidence shifts dramatically when he experiences extreme emotional turmoil. Following Nya's apparent death in the Seabound storyline, a grieving Jay demonstrated extreme agility by leaping between buildings. Later, during the Crystallized arc, his power output matched Kai's, and in Dragons Rising, a disgruntled Jay successfully overpowered Cole. Most notably, the character Ras explicitly describes a broken, rogue Jay as a greater obstacle than all the other ninja combined.

This fan theory provides a fascinating look at character design and narrative consistency within the Ninjago universe, proving that Jay's perceived weakness is actually a deliberate reflection of his generally cheerful personality. Analyzing these intricate storylines adds depth to collecting and displaying sets from the theme. To keep your growing collection organized as you build and display your favorite characters, you might want to pick up a LEGO storage box to keep all your minifigures and extra pieces safe.
